.i WASTE-DELIVERY MEANs.

Applicaton'led November 14, 1923. ASerial No. 674,710.

To4 f/ZZ eli/tom t may concern Y Be 1t known -that I, HARRY TUNsTALL, a subyect of George V, King of England, and

a resident kof Fairhaven, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement lin vaste-Delivery Means, of `which the followingis a specification.

In Letters Patent issued to me No. v1,351,-v

v076, dated August 31, 1920, there is shown a combing machine in which the waste is removed from the kcylindrical combs by .n'ieans of rotary Abrushes and is delivered upon a cylinder'runningthe length of thel machine to which it is drawn by suction in the usual way. I have found that while this arrangement isV 1n many respects satisfac- V tory, in a machine where, there are a number of heads, each containing in itself Va complete combing mechanism so that the amount of waste is considerable,'especially where the mechanisms of these said heads are arranged back to back as in my said patent, a better result can ybe secured by the means herein Y after described. In ,my description I have shown only so much of a twelve-headed comber of thc character described in my said patent as is necessary to explain my invention, and so far as therparts shownare similar to those in my said patent I have given to them their corresponding reference characters. My invention is shown in the in its preferred form,

Figures 1 and 1a show partly in side ele-` vation and partly in section mechanism emv bodying my invention, it being' understood that Fig. 1l is an extension tothe left of the mechanism shown in F ig.. 1,A 7 F igs, 2 'and V2f* are plan views similarly arranged ofV my delivery mechanism, portions thereof being in section.

Fig. 3 is a view partly in cross section showing oneof the end plates of the box viewed from the outside; y r

Figa a section on line lf-4 of,Fig.l2, and Figs. y5 and Gare views-of the two ends of so much of Vmysa-idlcombing machine vas relates to my .present improvement, together with the means for operating my improvedrawings Y ment. 1

cylindrical combs and .their brushes are loocated. One box is provided for each pair ofV heads. This resembles the box Gel in my saidfpatent except that its ends are made in three sections, a central section 14 tov which is attached as at 18 two side sections 15 and 16 and the outer walls 15 and 16 of this box carry inner Ywallsv 6&1 to conform somewhat in shape tothe outer surfaces of the cylindrical combs andy so reducethe capacity and improve the utility of the box.v The cylindrical combs 62 are mounted on shafts 63 which may be operated in any convenient way, kfor example, asV shown yin my said patent or preferably in the way yshown in a companion application hereto Serial No. 674,708. So also the brushes G6 are mounted on shafts 67 and are rotated in iopposite directions toward eachother as in said patent to receive and carryidown the waste. The waste brushedfrom the cylindrical combs is thrownby the brushes down toward the Y bottom of thebox 64 and is drawn by suc' tion against and betweenrotary drums129` rotating' in opposite directions andV between which it is drawn out ofthe box. i

yI preferably use two drums between which pthe waste@ is drawn. `Each drum comprises an outer cylinder 1 which is perforated around its circumference within the cas ing and withinit is an `imperforate cylindcrr2 in which, however, there are openings 3, 4, 5, 6, 'i" and 8, one opening for each pair of heads. Preferably some ofthese openings are in lone cylinderand some in the other cylinder for the better *utilizationy of the suction. As shown, openings 3, 4 and 5 are in one cylinder and openings 6, 7 and 8 in` the other cylinder. These openings are of substantially the length of the heads. At one end of the drums is located a fan 139 which may be of yany desired constructiony and hence is not shown invdetail. The pur pose of this fan is to create a suction in the drums which will cause the vwaste to be drawn between the cylinders 1 which as they rotate toward each other will 'compress theY waste and'feed it out from the box, and also@ to withdraw any dust and lint which may fall into the interior cylinder" 2 through the openings 3, etc. The fan 139 is connected toboth cylinders 2 by a funnel-.shaped connection 139a large enough at one end to receive the ends of the two Ycylinders' 2 and at the other end small enough to enter the fan casing 13,9;l

The outer member or cylinder 1 ot each drum 125.) is caused to rotate intermittently by means oit' intermeshing gears 9 and 10, each attached to one end ot' a cylinder 1, which are suitably mounted in bearings on a support 11 to rotate therein. A pinion 132 mounted on shatt 133 in a hanger A1 trom the trame A engages the gear 10 and is operated intermittently by means ot a atchet 13st. also on shait, 133 and pawl 135. This pawl is mounted on a lever 1Q also :tulcrumed on the shaft 133 and operated by means of the link 13T connected to a rocker arm 13 hung on the rock shaft 103. By this means as the arm 13 is rocked it mores the pawl 135 to give a step-by-step motion to the ratchet 131 which turning the pinion 132 rotates the gear 10 which in turn rotates the gear 0, thus turning the cylinders 1 ot the drums.

There are two rock shafts 103 shown herein and in my said patent, both supported in brackets 101. Both rock shatts are operated by links from a crank disk 105 on Shait S. As shown in Fig. G, however, l use but one link 10T and connect both rocker arms 10S, carried by the rock shafts 103, by a link 1082 As suggested above, I preferably equal ine the suction between the front and rear ends oit the drums by dividing the openings fi, 4l, etc., which connect the interior ot the drums with the interior of the boxes, between the two stationary cylinders i2 as r shown, and I also graduate the size ot said openings, those near the Ytan being smaller than those 'farther away 'from the fan. This is indicated in the drawings where the openings which in each case are approximately the length ot a head, vary in width so as to render eti'ectire an increasing number ot perforations in the cylinder 1 as air passages 'from the interior oi its box-to the interior et the cylinder 2. Small openings Gail in the top (-ll ot the bonY provide air inlets tlirough which air will pass into the box.

Each box covers the cylindrical combs for one pair ot heads and the ends of each box are prete ably made as shown in three parts, a central part 11 and two side parts 15 and 1G, these several parts being bo ted together or otherwise attached as at 1S, the whole being mounted upon the :trame A.

rl`he tan 135) has a delivery opening 139 through which the dust and lint witlnlrawn Ll'rom the interior olf the imperforate cylinders is blown oil.

lli'hile the construction is desirable for six double heads, i. e. twelve heads back to back as in my said patent, each having a nipper Ylrame and a top comb, the number and size ot the openings may be varied according to circumstances, and my drums may be tui-ther modilied in like manner :for

aJ machine ot the usual construction having single heads.

It is ot course understood that the details o'l' my machine may be varied without de parting 'from my invention. The above construction I have `found practical in every way and useful in a double comber ot the hind described.

It will be noted that the openings 0G"L 'for the brushes in the box ends are oval. This allows tor a slight vertical :uljustment tor the brushes as they get worn. In practice the brushes are long enough to fill closely the space between the ends ot' the casing so as to reduce toa minimum the income ot air through the openings 00 into the boxes.

lVhat l claim as my invention is z- 1. A waste-delivery mechanism comprising a suction tan, a pair ot drums located side by side connected to said tan, each drum comprising an outer perforated rotatable member and a substantiallyY closed inner stationary member, means 'lor rotating said outer members toward each other, and open ings in said inner members spaced apart and located to provide air passages through each drum at points contiguous to the other drum.

Q. In a machine ot` the kind described, a casing having an opening at the bottom, two drums located to close said opening, said drums each having an outer perforated rotatable member and means tor rotating said outer members toward each other whereby waste from said casing and engaging said members will be withdrawn trom said caf ing, stationary substantially closed inner members provided with openings, and suction means adapted tocanse a Suction trom the interior et Said casingr through said open ings and perilorations anddraw the contents ot said casing to said drums.

3. lu a libre waste-'delivery mechanism comprising a casing, two drums each comprising an outer perforated rotary member and an inner stationaiy4 member prcn'ided with openings at points along its length, said drums being located side by side at the bottom of said 'asing and in close proximity to each other, a suction means located at one end o'f said drums and adapted to withdraw air Yfrom said casing, said openings being graduated in size whereby the suction at the several openings alongl said drums will be substantially equally distributed.

i. In ar combing machine a ian, a pair oidrums located side by side, each drum eoinprising an outer perforated rotatable member and an inner cylindrical stationary member having openings located lo eooperate with said lan in providing suction through said drums and means for rotatilr),l said outer members towards eachy other.
